Deeper analysis
CVE-2026-32484 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the BoldGrid weForms plugin for WordPress, enabling Object Injection. The issue affects weForms versions from n/a through 1.6.26 and was published on 2026-03-25. It carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact across confidentiality, integrity, and availability.
An attacker with low privileges, such as an authenticated WordPress user, can exploit this vulnerability remotely with low complexity and no user interaction required. Successful exploitation allows Object Injection through untrusted deserialization, potentially leading to high-impact outcomes including unauthorized data access, modification, or disruption of the affected system.
